The DC150 model is an overhead door closer with variable force (EN 2-3-4), available in the standard version (it performs the door closing function only) and in the hold-open version (in addition to closing the door, it allows blocking at 90 °). All models are complying with the CE EN 1154 standard, available in black and silver finish and can be installed on right-hand or left-hand opening doors.
